Please check that the needle is in the right way, flat shank to the back and all the way up into the housing. This would cause the stitches to not form.

Failing that, if it is not picking up the bottom thread, then the timing could be out and it would need to visit the shop.

My stitching on Brother ls 2020 sewing machine is loose. How do I fix the problem


Without more description of the stitch symptoms, the only suggestion is that the tension is too loose. Whether it is the upper, bobbin, or both tensions, we cannot answer without more information.

Machine won't zig zag even though the needle goes from side to side the line of stitching is straight.


put in a new needle
rethread the machine top & bobbin--use every thread guide
make sure the zig zag settings are correct
it's also possible that the machine could have a worn or damaged gear or cam--which would have to be checked at a sewing machine shop

Bernina activa 210 won't zigzag and has bobbin issues on straight stitch


it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop
is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?
is the bobbin in correctly?
is the bobbin warped?

Why won't my Bernina Activa 140 sew the blind hem stitch?


Are you absolutley sure you're not getting a problem with stitch formation on, for example, wide zig-zag. Check again, using a different colour top and bottom and make sure that the stitch is being formed properly with only the top colour on top and bottom colour on the bottom. It sounds as though the bottom loop is not being picked-up by the hook properly. Make sure you've thoroughly cleaned-out any fluff under the stitch-plate and remove the hook/shuttle and give the hook race a good clean and give it a single drop of oil, even if you've got the lightweight part-plastic hook/shuttle fitted.

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please


  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    Timing
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    Thread
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

How do you adjust the bobbin


Hello

Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.

Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.

Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.

Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.

Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.

Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.

Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

After I sew I can pull the bottom stitching right out. What causes this? Help


The problem is most likely thread tension. First try loosening the upper thread tension (numbered wheel on left side of most machines), if this doesn't rectify the problem then check the bobbin case tension. Correct bobbin case tension can be verified by holding the bobbin case with bobbin inserted and thread extended several inches. If you grasp the thread the bobbin case should not descend rapidly (fall) but should unspool slightly when thread is quickly tugged upward. Please refer to attached picture or your owner's manual.azcouture_1.jpg

Lower thread keeps jamming even though bobbin case is clean and tension on thread has been adjusted.


Hello,
Here are some things to try.

* Re-thread your machine

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

Also, before you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.
I hope one of these solutions help.
